The reformist‐moderate and the conservative discourses have co‐existed and contended for primacy in the Iranian foreign policy since the 1979 revolution. The 2015 Joint Comprehensive Plan of Action (JCPOA), also known as the Iran nuclear deal, has been at the core of this discursive contest in recent years. This article investigates how Iranian conservative tweeters delegitimized the JCPOA and President Rouhani's nuclear diplomacy. We use Van Leeuwen's discursive construction of legitimacy (2008) to analyze three popular conservative Twitter accounts. Findings show that the Iranian conservatives used the strategies of authorization, moral evaluation, and rationalization for legal and political criticism of the JCPOA, offending Rouhani's administration and allies, and questioning their political competence. This research partly reveals the conservatives' anti‐negotiation and anti‐West logic and their refusal to offer a diplomatic alternative to the JCPOA.
